The 'High School Musical' and 'The Greatest Showman' star has had many, many injuries in the past few years.

Zac Efron blew up the internet last year, after a picture of him looking very different surfaced online. Many speculated that the star had gone under the knife for some pandemic procedures to his face, but it turns out his swollen look was actually more painful than you might think - he smacked his jaw while running around at home.

The 34-year-old had a chat with Men's Health about #JawGate this week, explaining that he didn't even realise he was trending online last year. Efron, you see, is not on social media, so he completely missed this whole conversation. That is until his mom asked him about it.

In the interview, Efron said he "shattered his jaw" while "running through his house in socks and slipped, smacking his chin against the granite corner of a fountain". He then lost consciousness, and woke up to his chin bone "hanging off his face". Yikes.

When pressed for more information, he says the masseter muscles, used for chewing, work together with the other muscles of the face "like a symphony". When he was injured, however, the muscles on the inside of his face and jaw had to compensate and so he sought out a specialist to do physical therapy with him. However, he took some time off from doing this in Australia, which might not have been the best of timing. He says: "The masseters just grew. They just got really, really big."

Efron claims he knew nothing about the conversation happening online about his jaw-dropping new look, and not until his mom called to ask him whether he'd had plastic surgery did he realise he was quite a big talking point. Saying he's largely been off social media since the age of 17, he added: "If I valued what other people thought of me to the extent that they may think I do, I definitely wouldn’t be able to do this work."

In terms of romance, the actor says that he's "taking time to focus on, you know, self-fulfilment and trying to find my groove", adding "I know that probably when I meet the right person, it’s going to be when I least expect it."

Catch Efron in Apple TV+'s 'The Greatest Beer Run Ever', which releases on September 30.
